  In my boxes of chips, I've found revision D2.14R5 firmware for the Sun
4/600 CPU board.  The chips have labels written in my handwriting, and I
very vaguely remember upgrading several 4/600s in the 1990s.  I think
this was for Ross HyperSPARC compatibility but am not sure.

  I've read the EPROMs and have their contents as files, and I have
several complete sets (of four) of the EPROMs.  If anyone is running a
4/600 and needs these, let me know.
